IilIECJIlCATION forming part of Letters Patent N o. 722,975, dated March17, 1 903.

Application filed December 22, 1902. Serial No. 136,173. (N0 model.)

To all zul-1,0177, t may concern:

Be it known that I, GEORGE P. HALEY, a citizen of the United States,anda resident of Mexico, in the county of -Audrain and State ofMissouri, have invented a new and lmprved Staple-Puller, ot` which thefollowing is a full, clear, and exact description.

The object of'v the invention is to provide a device for drawing staplesfrom the posts or other supports for fence-wirev and to soconstructtt-he device that it will not only be simple, havingbut fewparts, and strong and readily manipulated, but wherein the device iscapable of drawing straight out the longest fence-wire staples and ofretaining the drawn staples until purposely removed from the device.

The invention consists in the novel construction and combination. of theseveral parts, as will be hereinafter fully set forth, and pointed outin the claims.

Reference isto be had' to the accompanying drawings, forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the figures.

Figure 1 is a side elevation of the improved device. Fig. 2 is a frontelevation ofthe same. Fig. 3 is a section taken practically on the line3 3 of Fig. 1, and Fig. 4 is a section taken on the same line as in Fig.3 through a slight modification in the lower portion of the grip-leverused in connection with the device.

The shank A is provided with a handle 10 at one end and with a clawhead1l at the opposite end, including a hammer-section 12. The outer edge 13of the claw-head, which 'is the lower edge in action, is convexedfandthe inner edge 14 of the claw-section of the claw-head, which is theupper edge in action, is straight, as shown in Fig. 1, and saidclawsection terminatesin apoint 15. A clamp B is used in conjunctionwith the claw-head.

This clamp is U-shapedin cross-section and is bifurcated at its innerends, the shank A being received between the members of the bifurcatedsection ot said clamp, and the clamp is pivoted to the shank by a pin 16or its equivalent. The outer end of the clamp is downwardly andoutwardly inclined, the inclination being away from the shank and indirection ofthe point ot the claw-head, and

teeth 17 are projected from the loweredge of said clamp at its outerend, the teeth having a corresponding inclination to the inclination ofthe outer end ot said clamp. The clamp is furtherprovided with a lug 13upon its upper surface.

A connecting-rod 19 ispivotally attached at one of its ends to the lug18, and the other end of the connecting-rod is pivoted between thebifurcated lower section 20 of an anglelever 21. The shank A is passedbetween the members of the bifurcated portion of the lever 21, and thelever is pivoted to the shank on a pin 22, passed through the'bifurcated portion of the lever at a point near the eenter thereof, Theupright or grip section of the angle-lever 21 isnormally held at anangle to the shank through the Vmedium of a spring 23, engaging withthe-inner face of the said grip-section of the lever and the rear edgeof the shank. VThis spring may be a strap-spring, as shown in Fig. 1,orsaid spring may be a coil-spring, as shown in dotted lines at 23a inFig. 2. The bifurcated or pivoted section of the grip-lever may beconstructed as'shown in either Figs. 3 or 4., In either case the saidsection comprises two parallel members a and a', and in one'instance theinemhers extend parallel and are spaced throughout their length, whereasin-'theother case the outer ends of the members are brought closelytogether.

In operation the point of the Vclaw-head is introduced beneaththeibowsection kof the staple, and the point is driven well beneath saidstaple by striking the hammer-section of the claw-head, and at the'sametime the gripsection of the lever is carriedup close to the handle,bringing the teeth 17 of the `clamp over and at each side of the pointofthe clawhead and the point of the claw-head between the members ofsaid clamp. The shank is then rocked upon the convexed surface 13 of theclaw-head, Iwhich surface 'affords sufficient leverage to enable theoperator to draw straight out the longest' staple in use on a wirefence, enabling-said staple to be used again. The clamp will hold thestaple upon the claw-head as long as the grip-section of the lever isparallel with the handle of the device. Thus the staple will loeprevented from dropping to the ground; but said staple ICO may be freedfrom the device as soon as the lever 2l is released.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- Y 1. A staple-puller, consisting of a shank providedwitha claw-head having a con vexed outer face adapted as a fulcrurn, aclamp pivoted upon the shank and adapted to receive the point of theclaw-head, a lever alsopiv-f oted upon the shank, and a connectionbetween the lever and said clamp, for the purpose set forth.

2. In astaple-puller, ashank provided with a claw-head having its outeredge convexed to form afulcrum, a clamp U shaped in crosssection andhavinga pivotal attachment to the shank, and extending over the inneredge of the said claw-head, said clamp being provided with teeth at itsouter end, a springcontrolled lever also pivoted to the shank adjacentto its handle end, and a rod connection between said lever and saidclamp, for the purpose set forth.

3. A staple-puller, consistingof a shank provided with a claw-headincluding a hammer-section, the outer edge of said claw-head beingoonvexed throughout its length, the claw-section of the claw-headterminating in a point, a clamp U-shaped in cross-section, pivoted uponthe shank adjacent to the inner face of the claw-section of theclaw-head and extending over said section, the outer` edge of said clampbeing beveled away from the shank and in direction of the point of theclaw-head, the outer end of the clamp being provided withdownwardly-extending teeth also having an inclination downwardly indirection of the point of the claw-section of the claw-head, anangle-lever pivoted to said shank adjacent to said handle-section, aspring having bearing against the grip-section of said lever andadjacent edge of the shank, and a connecting-rod pivotally attached tothe pivoted member of the anglelever and to the said clamp, for thepurpose specified.

GEORGE P. HALEY.
